The swivel knife holder assembly includes a shoulder screw defining an axis, and having a proximal threaded end and a distal head, and mounted on the shoulder screw is a bobbin assembly. The swivel knife holder assembly also includes a shell defining an interior, and having a distal opening and a proximal opening. A core is secured in the interior and is coupled to a knife for cutting fabric material. The proximal opening of the shell is defined by a flange and houses the shoulder screw therein. Threadably coupled to the proximal threaded end of the shoulder screw is a stem. The stem secures the bobbin assembly within the shell and also includes a mounting surface for engaging a reciprocating drive mechanism.

A printer configured to cut recording paper with a fixed blade and a movable blade has a push member configured to push out the movable blade or racks provided at both longitudinal ends of the movable blade, to expose a blade of the movable blade, and the push member is fixed in position while the blade is exposed.

A cutter unit includes a first frame, a fixed blade, a movable blade, a movable blade drive mechanism and a pressure mechanism. The fixed blade has a first cutting edge portion. One end portion of the movable blade has one end configured to cut a cut item in cooperation with the first cutting edge portion. The second cutting edge portion and the first cutting edge portion contacting with each other at a first point and a second point. Another end portion of the movable blade has a contacting portion in contact with the first frame at a third point. The first point, the second point and the third point define an imaginary triangle. The pressure member presses the movable blade at a pressure contact position so that the movable blade presses against the fixed blade. The pressure contact position is positioned substantially within the imaginary triangle.

An image recording apparatus includes an operation panel, a sheet conveyor, a print head, a cutting device, and a sheet discharge port. The operation panel is disposed at a first-side face of a housing in a particular direction that extends from a first side to a second side of the image recording apparatus. The sheet conveyor is configured to convey a sheet along a conveyance path in a conveyance direction. The print head is disposed downstream of the sheet conveyor in the conveyance direction. The cutting device has a cutter for cutting the sheet. The sheet discharge port is open at the first-side face of the housing. At least a part of the sheet passes through the sheet discharge port when the sheet is discharged from the conveyance path. The cutter positioned below the operation panel is exposed to an outside of the housing through the sheet discharge port.

An image recording apparatus includes a housing, an operation panel, a sheet conveyor, a recording device, and a cutting device. The operation panel is disposed at a first-side face of the housing in a first direction. The first direction is orthogonal to a vertical direction and extends from a first side to a second side of the image recording apparatus. In the first direction, the cutting device is closer to the first side of the image recording apparatus than the recording device is and closer to the second side of the image recording apparatus than the operation panel is. The cutting device includes a cutter, and a cutter carriage to move with the cutter mounted thereon along a second direction orthogonal to the first direction and the vertical direction. The operation panel overlaps a movable area of the cutter carriage when viewed in the first direction.

A printing apparatus includes a case configured to receive roll paper of a rolled recording medium, a cover rotatably attached to the case to be used to open or close the case, a transport section including a transport motor provided to the case and a transport roller provided to the cover, the transport section being configured to pull the recording medium from the roll paper and transport the recording medium along a recording medium path, and a cut section including a first blade and a first blade motor configured to move the first blade provided to the cover and a second blade provided to the case, the cut section being configured to cut the recording medium. The first blade motor includes a first blade motor shaft, and the first blade motor is provided to the cover such that a first extension line extending from the first blade motor shaft and a second extension line extending from at least part of the recording medium path in a width direction of the recording medium intersect each other when the cover is closed.

A printing apparatus, having a conveyer configured to convey a recording medium along a first conveying direction, an image recorder to record an image on the recording medium supported by a supporting portion, a liquid storage arranged on an outside of the supporting portion in a direction intersecting with the first conveying direction, a cutter assembly to cut the recording medium, and a controller, is provided. The controller is configured to move the cutter assembly to an outside of the supporting portion in a scanning direction, which intersects with the first conveying direction, to cut the recording medium; and control the cutter assembly to stand by at a standby position located on a side of the supporting portion opposite to the side, on which the liquid storage is arranged, on the other outside of the supporting portion in the scanning direction.

A medium cutter includes a conveyor configured to convey a medium in a conveyance direction, a cutter configured to cut the medium from one end of medium in a cutting direction orthogonal to the conveyance direction, a first holder movable to contact a first surface of the one end of medium, and a second holder configured to contact a second surface of the one end of medium opposite the first surface. The first holder is disposed downstream of the cutter in the conveyance direction, and the first holder moves to the one end of medium to pinch and hold the one end of medium between the first holder and the second holder.

A printer configured to cut recording paper with a fixed blade and a movable blade has a blade unit including the movable blade and a slider to which the movable blade is attachable, and the slider includes: a contact part configured to contact the movable blade; a flexible part formed thinner than the contact part; and a first protrusion provided on the flexible part and configured to engage with a first opening provided in the movable blade.

A cutter unit configured to cut a recording sheet to be advanced toward a forward side in an advancing direction, includes: a fixed blade, which includes a fixed blade edge, and is provided on a first surface side of the recording sheet; a movable blade including: a movable blade edge opposed to the fixed blade edge in a cutting direction crossing the advancing direction; and a sliding surface, which is provided on a backward side in the advancing direction, and is configured to be slid on the fixed blade; and a rack holder capable of reciprocating along the cutting direction, the rack holder including: a movable blade holder configured to support the movable blade; and an urging member configured to urge the movable blade to the backward side in the advancing direction.
